The bright secret of battery life

Published

on

On most smartphones in active use, batteries last little more than half a day. But there is a simple secret to the real battery hog, and how to double that life, writes ARTHUR GOLDSTUCK.

You know how it goes when you first get a new smartphone. Battery life is amazing for the first few days, often lasting well into the night. Then, as you download more apps and use them actively, you find yourself scrambling for a power bank or charging point by lunchtime.

We keep hearing that battery life is the next frontier of smartphone technology, and then we keep seeing dramatic advances in every aspect of the handset BUT battery life.

In the good old battery days of a decade ago, a Nokia 6310i gave you seven days’ talk time and a month on standby. The rapid advance of smartphone technology has meant that average battery life has rapidly gone down, instead of increasing, because so many more components and functions have been built on the same old batteries.

The Nokia 6310i featured a talk time of up to a week.

Now, however, battery management functions, such as those on new Samsung, LG and Huawei devices, help to identify which apps drain the most power, and to shut down the offending tools.

But, strange to say, this doesn’t keep our phones going longer. As we keep opening new apps that we hope are less demanding, or keep open some of the apps that are indicated as having low power demands, the battery drainage continues at the same high rate.

This happens particularly while one is driving, and using navigational apps like Waze and Google Maps. The assumption that tends to be made is that it is not the app itself that is resulting in heavy battery use, but the need for the maps to be updated continuously. This results not only in an ongoing data flood, but also requires the phone to keep polling the 3G or LTE masts at base stations along the route. Surely the prime reason the battery is dying!

Android power management apps help increase battery life.

The truth is a little simpler and a lot closer to home.

The reason Waze appears to chew up battery life faster than a puppy destroying a slipper is because it keeps alive the real battery hog: the screen display.

Check that battery management tool again: it can almost be guaranteed that half the battery usage in any given period is coming from the display. The bigger the screen, the more the display demand, and the faster the battery drain.

For this reason, entry-level smartphones with 3.5-inch screens tend to have far more battery life than the average 5-inch or 5.5-inch flagship devices. Compact editions of the Samsung Galaxy and Sony Xperia phones last longer than their bigger siblings. This is counter-intuitive merely because we expect to get better performance when we pay more.

The exception to the rule appears to be the giant-sized phablets: the 5.7” to 6” behemoths. But there is a simple reason for that, too. Most of these phones have oversized batteries, specifically to compensate for the giant displays.

It’s not an industry secret, either. Manufacturers continually point out this truth, but usually in the small print, as an afterthought, or somewhere offstage after the big launch.

All of this means that there is also a simple secret to extending battery life, while we wait for the scientists and engineers to catch up to our needs.

Every time you finish using the handset, whether for a call, a WhatsApp message or a Facebook peek, simply click the On/Off button briefly – that is, not long enough to switch off the phone, but merely to turn the display dark.

If that doesn’t at least extend your battery life into the evening, something else is going wrong with the device, or a rogue app is indeed going puppy on the battery slipper.

Cisco Security Connector

With all the malware, viruses and trojans doing the rounds, it is difficult for users and enterprises to ensure that they don’t become targets. Cisco, in collaboration with Apple, has brought out its Cisco Security Connector to protect users. The app is designed to give enterprises and users overall visibility and control over their network activity on iOS devices. It does this by ensuring compliance of mobile users and their enterprise-owned iOS devices during incident investigations, by identifying what happened, who it affected, and the risk of the exposure. It also protects iPhone and iPad users from accessing malicious sites on the Internet, whether on the corporate network, public Wi-Fi, or cellular networks. In turn, it prevents any viruses from entering a company’s network.

Platform: iPhones and iPads running iOS 11.3 or later

Expect to pay: A free download

Stockists: Visit the Apple App Store for downloading instructions.

 

Diski Skills

The Goethe-Institut, in co-operation with augmented reality specialists Something Else Design Agency, has created a new card game which celebrates South African freestyle football culture, and brings it alive through augmented reality. Diski Skills is quick card game, set in a South African street football scenario, showing popular tricks such as the Shibobo, Tsamaya or Scara Turn. Each trick is rated in categories of attack, defence and swag – one wins the game by challenging an opponent strategically with the trick at hand. Through augmented reality, the cards come alive. Move a smartphone over a card and watch as the trick appears on the screen in a slow motion video. An educational value is added as players can study the tricks and learn more about the idea behind it.

 

The game will be launched on 27 October 2018 at the Goethe-Institut.

Namola

With  recent news of kidnappings on the rise, a lot more thought is going into keeping children safe. Would your child know what to do in an emergency? Have you actually asked them?

Namola, supported by Dialdirect Insurance, is a free mobile safety app. Namola’s simple interface makes it an ideal way for children to learn how to get help in an emergency. All they need to do is activate the app and push a button to get help that they need, even when their parents are not around.

Parents need to install the app on their child’s phone, hold down the request assistance button, program emergency numbers that will automatically be dialled when the emergency button is pushed, and teach their children how and when to use the app.

Platform: Android and iOS

Expect to pay: A free download.

Stockists: Visit the store linked to your device.

 

Exhibid

Exhibid could be thought of as Tinder, but for for art lovers. The interface looks very similar to the popular mobile dating app, in that users swipe left for a painting that doesn’t appeal to them, or swipe right for something they like. Once an art piece is liked by swiping right, one can start bidding or make an offer on it. The bid is automatically sent to the artist. Should he or she accept the offer, the buyer makes a payment through the app’s secure payment gateway and the two are put in contact to make arrangements for delivery.

Platform: Android and iOS

Expect to pay: A free download.

New kind of business school

At a recent meeting, ALLON RAIZ, founder and CEO of Raizcorp, realised that in order for today’s youth to become entrepreneurs, teachers, the curriculum and the parents need continually expose them to entrepreneurial thinking from a young age.

Published

Several years ago, I found myself in a meeting with my business partner and two of my staff members. In front of us was a client who was sharing some of the frustrations in his business. At the end of the meeting, my partner and I were extremely excited about the prospect of two massive opportunities we had both independently identified while listening to the client. My two staff members, on the other hand, completely missed them. This led me to wonder what it was in my own and my partner’s backgrounds that allowed us to so easily spot opportunities while my two staff members remained oblivious … I realised that the difference was that my partner and I both had an early exposure to entrepreneurship while they didn’t.

Not long afterwards, I was delivering a lecture about how Raizcorp grows and develops small businesses at Oxford University’s Said Business School in my role as their Entrepreneur-in-Residence. I mentioned the above incident and spoke about my intention of going into children’s education with a view to providing an entrepreneurial perspective.

One of the professors in attendance asked me if I’d ever heard of a piece of research by Henrich R Greve called Who wants to be an entrepreneur? The deviant roots of entrepreneurship. It’s a pretty unfortunate title but a fascinating piece of research nonetheless. It highlights how certain contexts in childhood result in a much a higher probability of becoming an entrepreneur. For example, kids who participate in solo sports such as tennis or athletics are more likely to become entrepreneurs than children who play team sports like soccer and cricket. Conversely, your mother’s participation in the parent-teacher association has a negative correlation to you becoming an entrepreneur. I spent the rest of the afternoon in the professor’s office discussing other research papers that unequivocally proved that context during your childhood has a massive influence on whether or not you will follow the entrepreneurial route.

Another member of the lecture audience was a double-PhD from the USA who was completing her MBA at Oxford. After the lecture, she approached me and volunteered to help build a framework to incorporate entrepreneurship in the school curriculum without interfering with the formal requirements of the CAPS curriculum.

She spent nine months in South Africa working with me to build out a practical framework. The next phase of the plan was to find the right school at which to embark upon this journey. In December 2015, Raizcorp purchased Radley Private School and we began our entrepreneurial education adventure in earnest in 2016.

At the centre of the Radley philosophy is that the school (the physical building), the teachers, the curriculum and the parents are the “marinade” in which the kids need to soak in order to be continuously exposed to entrepreneurial thinking from a young age. The aim was that if, in future, the kids found themselves sitting in a boardroom with me and my partner, they too would be able to identify the opportunities that we did.

A big shift this year has been the launch of our Entrepreneurial Educator Guide (EEG) programme where we have been training our Radley teachers (whom we call guides) to understand entrepreneurship, business language, business concepts, financial documents and the like. (The EEG training makes use of Raizcorp’s internationally accredited entrepreneurial learning and guiding methodologies.) We have also employed a full-time staff member to ensure that these concepts are imbedded into all lesson plans and classroom activities.

Through my network at Raizcorp, I have been pleasantly surprised by the massive support we’re receiving from prominent entrepreneurs and businesses who want to participate in our Radley Exposure programme, where we take our kids of all ages on visits to different types of businesses so they can understand the difference between retail, wholesale, manufacturing, logistics and so on. Prominent businesspeople have put up their hands to come to the school and tell their stories of hard work, resilience and perseverance. This ties in beautifully with the 17 entrepreneurial concepts that we are instilling into our Radley learners (such as opposite eyes, lateral thinking and opposable mind), while never compromising on our quality academic offering.

As parents, we’ve all heard the terrible statistics about the probability of our kids finding jobs in the future. At Radley, we’re working hard to ensure that our kids have a legitimate and lucrative alternative to finding traditional employment and that is to become an entrepreneur. Radley is all about producing job creators and not job seekers!
